When both parents have genetic profiles (from uploaded DNA reports), the trial mating calculator shows a full coat color forecast for the expected offspring. See probabilities for every possible color and pattern combination based on Mendelian inheritance.
Beyond coat color, the trial mating tool helps you evaluate genetic compatibility. See which recessive alleles both parents carry, identify potential health concerns from shared lineage, and make informed decisions about which pairings will produce the healthiest, most diverse offspring.
Try different dam-sire combinations and compare the results. Review COI scores, coat color distributions, and pedigree overlap across multiple potential pairings to find the best match for your breeding goals.
